Located not even 500 meters off of BTS Punnawithi exit #4, this is far and away the nicest Air BnB I have stayed at in Bangkok. You can either coordinate the free shuttle with the host, pay 10 baht for a motoraxi, or simply walk there.
Sam and Areeya exercised a lot of patience with me via numerous texts upon arriving, as I was a bit fatigued and hungry. Both of them are easily accesible via WhatsApp or email.
The area: There is a 7-11 within five minutes walking, and street food vendors inside the parking area. The banana pancake lady is usually there 4-10PM daily. There are also a few local Thai restaurants across from 7-11 and on the way to the BTS. Bangkok Coffee is a nice cafe, and there is a legitimate 200baht one hour Thai massage next door. You can also find a pastry shop on the corner, and a lady selling produce at night.
The condo: clean, superb with all the modern amenities one could ask for: Electric cooking range, Flatscreen TV, plenty of storage space, desk area, comfortable big bed, lamp, small couch, table, clean bathroom with a good shower. I liked having a modern washing machine in the apartment, and the balcony exposed some nice views in the morning. I slept well here, and wifi was better than average. That is the standard for Thailand. The swimming pool was a bit cold but I dove in anyway. Refreshing.
You can stock up on groceries or venture in the world class food court at Tesco Lotus, right when you exit BTS On Nut, just two stops away from Punnawithi. Look for the entry upstairs...no need to even go far and you are there. There is a cinema and On The Corner Food Court across the street.
This will be my new to go to stay in Bangkok. Highly reccomended.
